LED clearance lights failing
I've noticed that after two years of use most of the LEDs in my rear corner clearance lights have failed. I believe they are a Bargman series #58 with 4 LEDs per unit. Of the four lights I'm down to...

I have LED boards from EBAY CHina that are rated to work with DC Voltages up to 12.2VDC or something like that...
These boards do not have a regulator circuit built-in. I purchased several spare boards in the event I started loosing interior lights LEDs since my RV produces up to 14.4VDC with its Converter/Charger unit. These were installed in 2009 replacing 12V incandescent 921 miniture Light Bulbs. So far I only have a couple of LED boards that have three led's in a roll on the board that are not working. I am assuming this board uses only three led elements in series for the 12VDC source. The remaining three groups are added in parallel to give out the specified light lumens specs.
I have seen My Truck DC Voltage go as high as 14.5-6VDC from the Alternator depending on the Battery charge state which might be out of range for some LED elements. Having four LEDs in the truck replacement safety light wired in series would add an additional DC voltage range specification without using any specific regulation circuits other than a single resistor perhaps... I have no idea if the LED elements are wired in series or parallel in the Truck Safety light replacement LED units.
I also have no idea what the designed DC voltage range spec is for a single Light-Emitting Diode (LED). Probably varies from the different manufactures. You would think these truck safety light LED replacements would be designed to work with the Maximum DC voltage the Truck 12VDC system setup will produce...
Just babbling on here with my limited knowledge of how a LED works.
I suspect wiring issues is the cause for LEDs not working in this case...
